An elevator system, test system, door blockage detection system, emergency call handler system, caller unit, monitoring system, and associated methods

An elevator emergency call handler system configured to:

• receive a call triggered by actuation of an emergency intercom button in an elevator car associated with the emergency call handler system;
• receive an indication of at least one of:
• the current configuration or status of an elevator door associated with the elevator car, and a movement or location of the elevator car;
• and
• selectively perform one of:
• sending a predetermined message to an emergency intercom system associated with the elevator car for output using the emergency intercom system, and
• connecting the emergency intercom system with an operator, depending on the received indication.

A caller unit configured to be mounted with respect to an elevator car, the caller unit being configured to be communicatively coupled to an emergency intercom button and an emergency intercom system of the elevator car, wherein the caller unit is further configured to:

• initiate a call to a remote call handler system on actuation of the emergency intercom button;
• send to the call handler system an indication of at least one of:
• the current configuration or status of an elevator door associated with the elevator car and a movement or location of the elevator car;
• and
• receive an signal from the call handler system and to output that signal using the emergency intercom system.

A caller unit configured to be mounted with respect to an elevator car, the caller unit being configured to be communicatively coupled to an emergency intercom button and an emergency intercom system of the elevator car, wherein the caller unit is further configured to:

• detect actuation of the emergency intercom button;
• trigger a test operation of the elevator car based at least in part on the detection of the actuation of the emergency intercom button;
• receive an indication of whether the test operation completed successfully;
• and
• initiate a call to a remote call handler system selectively based on the received indication.

An elevator emergency call handler system configured to:

• initiate a contact attempt to a remote operator periodically;
• record a response from the remote operator when the contact request is successful;
• and
• perform at least one of sending the recorded response to a caller unit mounted with respect to an elevator car for output using an emergency intercom system of the elevator car, and notifying another device of the success or failure of the contact attempt.
